    Marine Piles (Concrete, Steel, Timber) must be thoroughly cleaned and sound prior to installation of GUARDIAN 500 System Outer Cover as part of the GUARDIAN 500 System. Prepare substrate using high-pressure water blasting or similar mechanical means to remove all loose material including rust, scale, etc., and all other contaminants that can inhibit bond of the grout material.
    The GUARDIAN 500 System Outer Cover may be of one or two piece construction. If preferred, spacers / standoffs may be molded into the interior walls of jacket or otherwise these spacers may be added to the pile or jacket at the job site. If installing spacers on site, ensure a suitable adhesive, such as GUARDIAN Anchor Gel, is used for securing standoffs to the pile or jacket walls. Allow adhesive to cure, prior to installing reinforcement mesh and jackets. If grout material will be pumped into jackets, set ports into jackets as necessary and seal.Seal pile jacket tongue & groove joint with appropriate epoxy adhesive or similar compound by applying adhesive to grooved side of joint. Secure joint with self-tapping stainless steel screws or rivets.Establish a suitable bottom seal for jacket that will withstand the pressures developed during filling (pouring / pumping) of filler material. Bottom seal material is determined by environmental regulations and contractor experience. Bottom seal may be closed foam, oakum and expanding resin or other appropriate material including a relatively dry mix of the grout material.Larger jackets may require external bracing and strapping on the outside of the jacket to prevent bulging during placement of filler material into jacket. Place strapping system approximately every 300-500mm along jacket length, particularly at the bottom of the jacket.
